Abstract
A system and method for determining LEP ink conductivity are provided. A pair of electrodes is arranged to define a narrow gap there between. A non-conductive propeller rotates within the gap and causes liquid ink to flow over respective planar surfaces of the electrodes. The rotating propeller further prevents the accumulation of ink sludge on the planar surfaces of the electrodes within the gap. Electrical current is conducted between the electrodes. The electrical current is measured and the conductivity value of the ink determined there from.
